Doctor John Watson - Master of Fellatio

There's a serial killer in town. Four bodies in four weeks. All with their throats ripped out. They had several things in common but what caught Sherlock's attention was the fact that all four were clients of Irene Adler's. The most interesting thing? All four men had standing reservations with one Doctor John Watson who is supposedly so amazing at oral sex, he's booked weeks in advance.

Irene gets Sherlock an appointment to interview Doctor Watson about the victims but Watson has more than talking on his mind..
